An engineer will connect a pump to your central heating system. If it’s a Combi it will be connected at the pump head but if it’s a system boiler it will be connected at the circulation pump. This
pump will push Powerflush chemicals through the pipes, boiler and radiators.

This includes a chemical that will remove sludge and rust and inhibitor to help prevent future rust from forming. The engineer will collect and dispose of any contaminated water, debris or
particles that they remove from the system.

The engineer may also use special tools on the exterior of the radiator to dislodge stubborn blockages. They should be able to measure the temperature of your radiators before they have started
work and then show you the improvement after the Powerflush.

The whole process can last anything from 6 – 10 hours depending on the number of radiators in your home, the age of the system and the severity of the sludge in the system. The engineer may find
more problems than originally anticipated such as needing new parts to replace those that have been damaged beyond repair. Most Powerflush jobs can be completed in one day but some of the more severe
cases may require longer.

A qualified engineer will be able to perform repairs, replacements and carry out a Powerflush.
